Product Overview
The GE IC693ALG392 is a high-performance 8-channel analog current/voltage output module designed for GE Fanuc’s Series 90-30 PLC system and PACSystems RX3i platforms, delivering precise signal control for industrial automation applications. With support for 0–20mA, 4–20mA, 0–10V, and -10–+10V output ranges, the IC693ALG392 enables seamless integration with variable frequency drives (VFDs), control valves, and other modulating devices in process control, energy, and manufacturing sectors . Its 15–16-bit resolution (0.5µA for 4–20mA; 0.3125mV for voltage) ensures accurate signal reproduction, while 1,500V AC isolation safeguards against electrical noise and ground loops in harsh industrial environments .
As part of the Series 90-30 ecosystem, the IC693ALG392 interfaces with controllers like IC693CPU374 and power supplies such as IC693PWR330, forming a robust automation network. Its 8ms update rate and factory-calibrated linearity (<1 LSB deviation) ensure rapid and reliable signal updates, even in dynamic environments like chemical plants or power generation facilities . The module’s enhanced current mode includes open-wire fault detection, automatically flagging current drops below 4mA to prevent system downtime in critical applications like wastewater treatment or pharmaceutical production .
The IC693ALG392 operates on 24V DC external power (20–30V DC range) and draws 110mA from the +5V bus and 315mA from the +24V user supply, ensuring stable performance in demanding settings . Its compact form factor (110mm × 64mm × 30mm) and 0.35kg weight facilitate easy installation in space-constrained control cabinets, while IP20-rated housing protects against dust and accidental contact . Front-panel LED indicators provide real-time feedback on power status, channel activity, and fault conditions, simplifying troubleshooting in complex systems.

Main Features and Advantages
High-Density Signal Control
The IC693ALG392’s 8-channel design reduces rack space and cabling complexity, making it ideal for large-scale systems like automotive assembly lines or water treatment plants. Each channel supports independent configuration for 0–20mA, 4–20mA, 0–10V, or -10–+10V outputs, eliminating the need for external signal conditioning . This flexibility is critical in applications requiring mixed current and voltage control, such as simultaneous regulation of flow meters (4–20mA) and temperature setpoints (-10–+10V).
Enhanced Fault Detection and Recovery
The 4–20mA Enhanced range enables open-wire fault detection by reporting negative digital values when input current drops below 4mA. This feature is vital in oil refineries or chemical plants, where sensor failures could lead to safety incidents or production losses . Additionally, the module maintains output values during power interruptions (if external power remains applied) or resets to zero as configured, ensuring predictable behavior in unstable environments .
Rugged Industrial Design
With 1,500V AC isolation and IP20 protection, the IC693ALG392 withstands electromagnetic interference (EMI) from motors and welders, ensuring reliable operation in noisy environments. Its wide temperature range (-20°C to +70°C during storage) and flame-retardant housing further enhance durability in extreme conditions, such as offshore oil platforms or steel mills .
Easy Integration and Maintenance
The IC693ALG392 mounts directly onto DIN rails in Series 90-30 or RX3i racks, requiring minimal setup time. Its hot-swap capability allows replacement without powering down the system, reducing downtime during maintenance—a key advantage in 24/7 operations like food processing plants . Configuration is performed via software (e.g., Cimplicity Machine Edition) or a handheld programmer, eliminating the need for hardware jumpers or switches .
Compatibility Across GE Platforms
Designed for Series 90-30 and PACSystems RX3i, the IC693ALG392 works seamlessly with controllers like IC693CPU374 and IC697CPU780, as well as power supplies such as IC693PWR330. RX3i racks support firmware upgrades, ensuring compatibility with future automation advancements . For applications requiring higher performance, the IC694ALG392 (RX3i counterpart) offers 16-bit resolution across all ranges and advanced diagnostics .
